4:08pm

Bugscope Teamsample is in 'scope and pumping down

4:18pm

Bugscope Teamstill pumping down...

Bugscope Teamclose...

4:27pm

4:33pm

4:38pm

Teacherhi again! Students are here at 3 pm - same thing as yesterday - have to get them introduced to driving the scope...hope it works today :) THanks for adapting yesterday.

Bugscope Teamdoing our best

Bugscope Teamnew 'scope coming sometime soon, so the 'scope room is a bit more spare than it was when you were here

4:44pm

Teacherno worries...

4:49pm

Teacherawesome samples!!!

4:56pm

5:01pm

Guestwhoa! cool!

5:08pm

Bugscope TeamHey Everyone!!

Bugscope Teamwe are ready to roll

Bugscope Teamsorry I was talking with one of the grad students...

Guesthi guys!

Teacheralmost ready too!

TeacherStill not able to magnify from this end....just saying.

5:13pm

Bugscope Teamlet me know when you have questions

Bugscope Teamthat was not a question

Bugscope TeamI'm sorry -- I don't know why you're not getting control, or full control

Bugscope Teamplease if you find you cannot control ask T or me to drive

Bugscope TeamAwesome! Josh is here as well. Meaning you can ask anything about insects and we have it pretty much covered.

Bugscope TeamJosh can also drive...

Guestwhat are we looking at?

Bugscope Teamthis is the face of a cucumber beetle

Bugscope Teamyou can see one of the mandibles, which are forked, and you can see two pointy palps

Bugscope Teamand the frons, I think it is called -- the top portion of the mouthpar

Bugscope Teamts

Bugscope Teamin the center

Bugscope Teamplus one of the compound eyes, to the left

Guestokay so what is this?

Bugscope TeamPollen!

Bugscope Teamnow you can see a kind of chevron structure on this bee seta

Guestcan you zoom out please?

Bugscope Teamwith what looks like lily pollen on it

5:18pm

GuestSO COOL!!!!!!!!

Bugscope Teamso actually it is near the pollen basket on one of the hindlimbs

GuestIs that bee thigh?

Guestwhat part was the mandible ?

Bugscope Teamhaha Yeah Becca

Bugscope Teamback leg thigh, yes

Bugscope Teambeetle

Guestohh thank u!

Bugscope Teammandible = jaw

GuestDo you have any other pictures of pollen on bees that look different that lily pollen?

Bugscope Teamin humans the lower jaw is the mandible and the upper jaw is the maxilla

Guestcoool!

Bugscope TeamJessie not on this sample, that we have seen, yet

Bugscope TeamBecca I didn't mean to embarrass you. That was perfect.

Bugscope Teamyou can see a mite now!

Bugscope Teamupper left

GuestIs it a dust mite?

GuestI totally made a joke about that... we feel like you must be big brother now :O hahahahah

Bugscope Teamit has, like, a rock on its back, on its dorsal side

Guesthey we going to the spider now

Bugscope Teamyes bees often have mites, but that is not the bad type -- the Varroa mite

Guestwhat part of the spider is this?

Bugscope TeamFang

GuestWhy are there bumps on the end of the fang?

Bugscope Teamthis is one of the fangs, and where you see something that looks like an eye is where the venom is dripping out

GuestWould the mites harm the plants the bees are pollinating?

Guestcan you zoom out a bit?

Guestthank u for the mite info

GuestDripping? OH MY GOD.

Bugscope TeamMoe they are not plant mites; they would starve.

5:23pm

GuestWhat does the eye of the spider look like?

Guestwhat does the venom due? to prey? humans?

Guestdo spiders have hair?

GuestYes, is that hair?

Bugscope Teamthey have setae, which is similar to hair

Bugscope Teamthe venom causes a histamine reaction in people

Guestawesome.

GuestWhat kind of spider is this?

GuestWhat kind of spider is this? And can it's venom kill me.

Bugscope Teamsetae help the spider and other insects sense their surroundings

Bugscope TeamA dead one ;)

GuestHA. HA.

Guestcan we zoom out more and then back in

GuestCan we look at the ladybug next?

Bugscope Teamspiders have between 6-8 eyes

Bugscope TeamI would have told you it was a Daddy Long Legs before I saw the fang.

Guestwhy do some spiders have more eyes than others?

Guestso this is a deadly wolf spider? :O

GuestCan we see a spider eye? Pleeeaaase?

Bugscope TeamIt is a more classical kind of spider -- haha -- not sure what it is.

Bugscope TeamTheir venom is used primarily for subduing insect prey, so it typically does not affect mammals.

Guestaren't daddy long legs the most poisonous spiders?

Bugscope Teamthe closest we can come to a spider eye is an ocellus

GuestMake it so.

Guestwhat is an ocellus?

Guestwhat is an ocellus

GuestSo this is one of the eyes?

Bugscope TeamThey are not! thats actually a myth. they are harmless. In fact what most people in the US call daddy long legs are not even spiders at all, but a closely related group of arachnids known as harvestmen

Bugscope Teamthat about DDLs has been repeated often but I think it is still not true

Guestis that the eye?

Bugscope TeamI'm not 100% sure, but I imagine the different number of eyes relates to both the habitat and type of hunter the spider it

Bugscope Teamis*

Guestwow thats insane!

GuestCan baby spiders eat prey right out the womb or do they get fed by their mothers?

Bugscope Teaman ocellus is a simple eye that allows insects to sense changes in light intensity but not form actual images

Bugscope Teamthat is an ocellus, on the top of the head of a bee, but it looks like a spider eye

5:28pm

Guestcan we see a fly now, please?

Guestso insects don't have eyes, but instead ocellus?

Bugscope Teamwhen we look at spiders we have a choice between the top of the head where the eyes are and the bottom, with the fangs and the retention plan

Guestso do bugs actually not have eyes that see images or is that exclusive to bees and spiders?

Bugscope Teammany insects have both compound eyes which can form images and ocelli. The ancestral state is to have two compound eyes and three ocelli

Bugscope TeamChristina the ocelli are simple eyes, but most insects have compound eyes as well.

Bugscope Teamthe compound eyes are able to form images

Bugscope Teamyou can see a compound eye to the far left here

Guestwait - what do bees eat?

Bugscope Teambees eat pollen and honey

Bugscope Teammostly

GuestYeaaah stinger

GuestIt looks like a honey comb

Guestoh what???? that's cool. I didn't know they ate what they transported and made!

Bugscope Teamthe stinger is a preset

Guesthuh???

GuestWhat does that mean.

Bugscope TeamThe differences between bees, hornets and wasps are differences in behaviors and overall look

Bugscope Teamlooks like a honeycomb in part because it shares the same mechanical necessity.

GuestWhat is this? Is it the eye?

GuestPreset? like... what does that mean?

Bugscope Teamsorry -- it is one of today's presets, on the lefthand screen

Bugscope TeamBaby spiders can feed right after they leave the eggs, but mostly on small insects like little flies. Few few spiders have parental care

Guestwe got it now

GuestAre we near the stinger, or is THAT the stinger?

Bugscope Teamyou can see that it is serrated like a steak knife, or two of them; they slide side by side to cut into your skin

5:33pm

Guestomg it looks like a serrated sword!

Bugscope TeamBecca that is the stinger

GuestIt looks like a freakin' harpoon.

GuestWhat do baby spiders eat?

GuestBecause it is serrated, is that why it gets stuck and they lose them when they sting?

Guestwow that is soooo bad ass!

Guesty is the stinger cerrated?

Bugscope Teamthe recurved barbs are what make it stick into your skin

Bugscope Teambaby spiders eat small insects like flies

Guestbees die after they sting you right?

Bugscope Teamthey help cut and they help it stick into the skin

GuestDo wasps have non-serrated stingers? Is that why they're able to sting multiple times?

Bugscope Teamhoneybees die when they sting mammals, not when they sting other insectr

Bugscope Teaminsects

Guestwhat is the function of setae for a spider

GuestThey can eat right out the womb or do they get fed via mom?

Guestwhat type of bees are there?

Bugscope TeamBecca the stingers do seem to be less barbed

Bugscope Teamin wasps

Bugscope TeamBaby spiders usually are able to eat a short while after they hatch, and will fend for themselves without help from the mother, although in at least one species the mother will feed her young by letting them eat her alive

Guest& why don't bees die when they sting other insects?

Bugscope Teamwasps have slightly serrated stingers

GuestThank you, Scot.

Bugscope TeamThere

Guestcan we see another?

GuestDope

Guesthow do queen bees look different than regular bees?

Bugscope Teambut yes, the differences in serration is one reason why they can sting multiple times

Guestlet's look at a fly now??

Bugscope Teamthe queen be is a lot bigger than the female workers

Bugscope TeamSetae are an insect/spiders primary sensory structures. some of them are chemosensory and can detect chemicals in the air or on a surface, others are mechanosensory and can sense objects that they touch by bending.

Bugscope Teamis a variety of types of bee, and it is the honeybees that lose their stinger and the outboard motor-like pump that drives the venom into you; that kills the honeybee because when it comes out there's a big hole in the bee's body; it bleeds out

Guestawww

Bugscope TeamMosca ito

Guesti think it's fly time

Bugscope Teamthis is a small fly

Bugscope Teama mosquito

Bugscope Teamthe queen be has a very long pointed abdomen because she is fertile and can lay eggs

Guesthaha which is it a mosquito or a fly?

GuestDinner rolls. These look like someone smushed dinner rolls.

GuestWhat's the average lifespan of a wasp? And what about a bee?

5:38pm

Bugscope Teammosquitos are a type of fly

Guestthe what? eye?

Guestooooooh snap

Bugscope Teammosca means fly, so mosquito means tiny fly

Guestcute

Bugscope Teamhowever, the male bees also look different from the queen bee, they are also slightly larger than the worker bees and have bigger eyes

Guestwhy do they have bigger eyes?

Guestdo queen bees have a diamond on their back?

GuestI thought that queen bees had a little marking on their back?

Bugscope Teamit's like a tramp stamp

Bugscope Teama wasp lives around 20 days

GuestCan we see where the mosquito sucks blood?

Guesthow do wasps traditionally die?

Bugscope Teamokay this is a fly

Bugscope Teammales have bigger eyes in many insects species and the main reason is that bigger eyes mean that they have a better chance a finding a mate

Guestcool, thanks

Bugscope TeamRachel we were able to find the tip of two stylets, part of the fascicle, which is what the mosquitoes stick into your skin

GuestWhat's the difference between a regular fly and a horse fly? (Aside from the size difference)

Guesthow many female bees does a male bee typically mate with?

Guestare there gay bees?

GuestIs there a reason why mosquitos bite some people more than othes?

Bugscope Teamhere we can also see, on the body, a thoracic spiracle

Bugscope Teamone. then he dies.

Guesthaha awesome

GuestOk thanks!

Guestwhats a thoracis spiracle?

Guestbees die after mating?

GuestBecause I'm real sick of getting bitten by mosquitos.

Bugscope TeamUnless the marking was put there by humans, I don't believe queen honey bees have a marking on their back

GuestFor real, Laura

Bugscope TeamI don't think there are any gay bees, not really sure

GuestIs it because my blood is sweet?

Bugscope Teamno bees do not die after mating

GuestTasty tasty blood?

GuestLaura is actually a real sweetie

Bugscope TeamOnly the males die. they are kind of useless except for their sperm so once they've mated its kind of pointless for them to continue living anymore...

Teacherconversation is getting interesting!

GuestThx.

GuestWhat's your blood type, Laura?

Guestcool!

5:43pm

Bugscope Teamthe thorax is the body part in insects that the legs, head, and abdomen are connected to, kind of like a trunk in humans

GuestAre their gay insects?

Guesto positive

Bugscope Teamno it is not, every person has their own scent and some scents are more attractive to mosquitoes than others

Teacherlet's see more of the fly body - yes?

Guestor arachnids

Bugscope Teama thoracic spiracle is a breathing pore in the thorax

GuestFlies have 6 legs?

Guestso youre saying im attractive

Bugscope Teamyou can see the haltere now

Bugscope Team...yes...

GuestIt doesn't?! Wow.

Teachercan we take a look at the fly wing? A few folks want to see that - says Captain Korb

Guest;)

Bugscope Teamyes flies and all insects as adults have six legs

GuestROFLING love bugscope!

GuestK FOCUS PEOPLE

GuestBUGS

TeacherYes focus.......

GuestSo as babies they have less legs?

Guestwhat's a tipulid?

Bugscope Teamthis is the haltere -- a modified hind wing

Guesthow many wings do they have?

Guestthats where the general wing attaches? yes?

Guestmore than 2?

Bugscope Teamas larvae they have six legs as well, but also sometimes they have prolegs

Bugscope Teamyes as babies they have 6 legs - assuming they are hemimetabolous aka do not have a grub/caterpillar/maggot life stage

Bugscope TeamI don't think insects are sophisticated enough to consider themselves homosexual. there are male insects that will attempt to mate with other males of their species, but this usually occurs when males are super aggressive, and they most likely simply have mistaken the male for a female. this can occur in bedbugs and dragonflies for example. in dragonflies this is probably an adaptive behavior since some females have coloration that mimics that of a male. So some male dragonflies might be bi?

Guestthat's a cool picture

Bugscope Teama Tipulid is a crane fly. They look like giant mosquitos, but they do not bite you and will not bite you

GuestJOsh, thanks for the info, dude

Guestcool, thanks!

Guestwhat are we looking at?

Bugscope Teamthese are hypertrophied mechanoreceptors on the haltere

Guestwhat makes it a "crane" fly?

GuestScot, english please

Bugscope Teamok Dr K just a sec

Guestwhat's a spiracle?

Bugscope TeamThey have ridunculously long legs. like a crane... get it?

Guestspiral miracle?

GuestSpiracle is a breathing hole jessie

5:48pm

Guestcool

Bugscope Teamspiracles are openings to the insects respiratory system.

Guesti asked thatt already :)

Bugscope Teamsome of the key features of a crane fly are the long legs it has and it has a distinct face shape

GuestWhy are their legs so long? They always look so clumsy flying around with those long legs so, like, what's the purpose?

Bugscope Teamthe spiracles can be opened and closed, and they have fur around them, often, to filter out the dust so they do not get clogged easily

Guestcan flies get like bronchitis or asthma in their spiracles?

Guestleg modifications?

GuestCan you distinguish male or female flies by looking at them?

Guestwhat is that

Bugscope Teamnot sure, Adrienne

Guestcan insects get high?

Bugscope Teamyes male fly eyes are close together and those of females are far apart

Bugscope Teamdid Dr K ask you to ask that ?

Bugscope Teamthey can get high

GuestWait, but, seriously, why are crane flies legs so long?

Bugscope TeamIm honestly not sure why they have such long legs. many of them are aquatic as larvae and lay their eggs in the water, so perhaps it helps them land on the waters surface? sometimes I think its just to piss of entomologists who try to pin them for insect collections ( the legs fall off insanely easy)

GuestInquiring minds need to know.

Bugscope Teamwhat we see now are microsetae

Guestcan flies get like bronchitis or asthma in their spiracles?

Bugscope TeamJessie, not really, they can have mites invade the spiracles or perhaps damage to it. There are some bacteria that can infect the trachea, but it isn't asthma or bronchitis

Guestso these are the "not hair" hairs?

Bugscope Teaminsects with long legs often have them so they can step over larger things or as in ants, like leafcutter ants, they can lift larger pieces of leaves

GuestCan flies get mites too?

Bugscope TeamA professor in our department conducted a study a number of years ago where he gave honeybees cocaine and examined how it affected their foraging behavior :) it made them thing every flower they saw was the bees knees, if youll pardon the expression.

Guestare the mites parasidic or is there any sort of simbiotic relationship?

GuestSame question for spiders

Guestso cool!

TeacherAny chance we can see a BEE WING? Dr. K.

Bugscope Teamthey are not hair hairs of a different type -- they are not sensory

Bugscope Teamyoutube spiders on drugs sometime ;)

Guestwhat is the purpose of the bee claw???

5:53pm

Bugscope Teamhaha yeah we have some hamuli for you

Bugscope Teamit helps them grip surfaces.

Bugscope Teammost insects have claws; sort like why we have hands

GuestBEE WING PLZ?

GuestHow long is a bees pregnancy?

GuestDr. K said we have 5 mins

Guestcan we see a bee wing?

Bugscope Teamthis is both the fore- and the hindwing

Bugscope Teamof a bee

Guestthis is a bee wing? such craftmanship!

Bugscope TeamBees do not get pregnant, they lay eggs. I believe the fertilize the eggs as they lay them ( they keep reserves of sperm inside their body).

Bugscope Teambee's don't really have a pregnancy

GuestAre mites parasidic or is there some sort of symbiotic relationship with the host animal?

Bugscope Team*they

GuestWhat is the little zipper bit?

Bugscope Teamnow you can see the wings better

Guestwowzaaaaa

Bugscope Teamthere's a tear in the hindwing

Bugscope Teamsome mites are parasitic, others have mutualistic relationships with other organisms, and still others are free living. they are a very diverse group

Bugscope Teambees and ants, if they have wings, have four wings

Bugscope Teamalso wasps

Bugscope Teamunless theyve had an unfortunate accident

Guesthowmany different types of flies exist?

GuestDun dun DUN

Guestsweet deal

Bugscope Teamflies have two wings, and the haltere, which we saw earlier, beats with a rhythm opposite that the wings to kind of help balance them in flight

Guesti heart bees

GuestWhy are the wings paned?

GuestDoes that make sense?

Guestyou guys are awesome, thank you!!!

GuestYes, thank you!

Bugscope Teamthere are atleast 110,000 known species of flies, but it is very likely that there are more

GuestThank you!

GuestThank you!

GuestThank you!

Bugscope Teamthere are more than 150,000 described species of flies in the world

GuestThank you!!

GuestThanks you

GuestThaaaaaaaaaaaanks, dudes!

GuestThank you!!!

TeacherHey all - thanks!! We are going to sign off. Good luck with the new scope!!

Guestwow awesome thank you !!

Bugscope Teamhaha nice guys

Guestthanks!

Bugscope Teamthank you, everyone!

Bugscope TeamThank you all!!!

Bugscope TeamThanks for coming, hope you'll bee back soon :)

5:59pm

GuestBYEEEE

Bugscope TeamI'm sure you'll await the next session with much Ant-icipation

Bugscope Teamhope these puns arent tick-ing you off....

Bugscope TeamNext time we see you we expect to be running a new microscope.

Bugscope Teamthey mite be...

Bugscope TeamI don't have the admin chat - no problem Scott :) happy to help
